Problems solved by technology

Although semantic matching is more intelligent, its query efficiency is much lower than the longest prefix matching, and hardware processing and efficient forwarding cannot be realized
Introducing a semantic matching query mechanism to the NDN network to support multi-dimensional data of IoT applications will not only destroy the compatibility and interconnection with other NDN network devices, but also reduce the performance of forwarding efficiency at the network level

Embodiment Construction

[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0030] The current named data network system only supports one-dimensional naming rules, and lacks the ability to deal with multi-dimensional data characteristics of sensor networks. The query algorithm based on longest prefix matching cannot efficiently adapt to multi-dimensional requests from upper-layer applications, and it is also difficult to implement at the network level. Efficient content matching. On the other hand, using multi-dimensional...

Abstract

The invention discloses a multidimensional naming supporting method of a naming data network. Aimed at multidimensional characteristics of data of internet of things, the multidimensional data naming supporting method of the naming data network is provided. By designing a multidimensional naming middleware framework and a one-dimensional multiple component discretization original naming mechanism, NDN is added with an ability of multidimensional data supporting with the premise that NDN one-dimensional naming and the longest prefix matching of a network layer are not changed; by introducing content intelligence perception and name dynamic state mapping mechanism, an optimizing translation from a multidimensional content requirement to a one-dimensional content requirement of a user is achieved, therefore, network load and content obtaining delay are reduced, and user experience is improved.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a multi-dimensional naming support method for naming data networks. Background technique [0002] In recent years, in response to the many defects of the existing Internet, countries around the world have actively carried out research work on the future Internet, and some influential research results have gradually emerged, among which Named Data Networking (NDN) is an important representative. NDN has changed the current end-to-end communication mechanism of the Internet, separated the content from the terminal location, changed the user's focus from the terminal to the content, and realized a content-centric network system and communication mechanism. The NDN network adopts a service model based on content receivers and a communication model based on named data. By layering naming of network content, the interaction of interest packets (Interest) and data packets ...
